Situated in the idyllic downtown area of Old Port, Market Square Jewelers’ Portland location has been open since 2014. This store is their 4th location and after visiting, I already want to go back (or visit all their other locations). The store features sterling silver on one side and fine gold vintage and antique jewelry on the other. Rows and rows of rings line the window display, with a back case dedicated to charms both funky and meaningful. Their selection of all-original antique engagement rings makes it an ideal spot to find that special ring!
